Abstract

Cellular Vehicle-to-Vehicle (C-V2V) communications take autonomous driving technology to the next level by allowing a Vehicular User Equipment (V-UE) to receive Cooperative Awareness Messages (CAMs) from other V-UEs, and enable the V-UE to see beyond what is detectable by visionbased sensors, thereby preventing accidents and ensuring user safety. However, there remains a fundamental limitation in the conventional CAM broadcasting since a transmitter (TX) V-UE cannot confirm whether its CAM is successfully received at other V-UEs. Without a feedback process, a significant uncertainty arises in CAM reception, posing a critical threat to user safety. To address this threat, we propose Beyond-Vision, an effective C-V2V on-demand relay system that allows CAMs that are not well received at nearby V-UEs to be better received. Through simulation that reflects realistic vehicle mobility and road environments in urban scenarios, we verify the superiority of Beyond-Vision over the conventional C-V2V, which improves performance by up to 215% in terms of message reception ratio (MRR) within a communication range under Non-Line-Of-Sight (NLOS) channels.
